$123–$330 after Steam's roughly 30% cut, derived from the copies estimate and its price.

How many copies did Hot 21 sell?

Q: How many copies did Hot 21 sell?

149 to 242 copies, based on its 6 Steam reviews. This is a labeled estimate from the review count, not exact sales.

Estimated copies sold: ≈ 149–242; $123–$330 after Steam's cut $223–$507 before Steam's cut; from 6 reviews (6 user reviews); Only 6 reviews so far, so that range swings on one or two people. Read it as a hint, not a measurement.

Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

Did the prediction match what actually happened?

Games like Hot 21

A typical game among these

≈ 527k–714k copies

≈ $3.6M–$4.7M after Steam's cut

from ~9k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

5 of the 8 similar games are hits.

Best case: UNO at ≈ 1.9M–3.0M copies, ≈ $5.1M–$13.8M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 1 reviews in their first month; the range was 1 to 12.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Card Game (5 of 8) and Sports (5 of 8).
The winners: Winners here lead with Card Game + Tabletop, priced around $10. The breakout hits carry Multiplayer + Tabletop + Board Game; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2023, and none of them shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
